Currently regression tests for python 3 are disabled on MSVC, and these
tests fail with python 3, too, so we have some work to do to enable
both. Meanwhile, all the buildfarm hosts seem to be building with python
2 anyway, so this at least gets us some coverage.
Original patch from Michael Paquier, significantly modified by me.
With this patch the MSVC build and installation will work correctly with
the transforms. However the python transform tests for hstore and ltree
are still disabled pending some further adjustments.
Michael Paquier with some tweaks from me.
Switching the Windows build scripts to use forward slashes instead of
backslashes has caused a couple of issues in VC builds:
- The file tree list was not correctly generated, build script
generating vcproj file missing tree dependencies when listing items in
Filter.
- VC builds do not accept file paths with forward slashes, perhaps it
could be possible to use a Condition but it seems safer to simply
enforce the file paths to use backslashes in the vcproj files.
- chkpass had an unneeded dependency with libpgport and libpgcommon to
make build succeed but actually it is not necessary as crypt.c is
already listed for this project and should be replaced with a fake name
as it is a unique file.

This makes it possible to run some stages of these build scripts on
non-Windows systems. That way, we can more easily test whether file
moves or makefile changes might break the MSVC build.

The majority practice is to add -DFRONTEND in directories building files
that are, at other times, built for the backend. Some directories
lacking that property added a noise -DFRONTEND in one build system.
Remove the excess flags, for consistency.
Each of the libraries incorporates src/port files, which often check
FRONTEND. Build systems disagreed on whether to build libpgtypes this
way. Only libecpg incorporates files that rely on it today. Back-patch
to 9.0 (all supported versions) to forestall surprises.
Before, make check-world would create a new temporary installation for
each test suite, which is slow and wasteful. Instead, we now create one
test installation that is used by all test suites that are part of a
make run.
The management of the temporary installation is removed from pg_regress
and handled in the makefiles. This allows for better control, and
unifies the code with that of test suites not run through pg_regress.

These modules have to be installed so that the testing module can access
them. (We don't have that yet, but will soon have it.)

Modern x86 and x86-64 processors with SSE 4.2 support have special
instructions, crc32b and crc32q, for calculating CRC-32C. They greatly
speed up CRC calculation.
Whether the instructions can be used or not depends on the compiler and the
target architecture. If generation of SSE 4.2 instructions is allowed for
the target (-msse4.2 flag on gcc and clang), use them. If they are not
allowed by default, but the compiler supports the -msse4.2 flag to enable
them, compile just the CRC-32C function with -msse4.2 flag, and check at
runtime whether the processor we're running on supports it. If it doesn't,
fall back to the slicing-by-8 algorithm. (With the common defaults on
current operating systems, the runtime-check variant is what you get in
practice.)
Abhijit Menon-Sen, heavily modified by me, reviewed by Andres Freund.
Now that we use CRC-32C in WAL and the control file, the "traditional" and
"legacy" CRC-32 variants are not used in any frontend programs anymore.
Move the code for those back from src/common to src/backend/utils/hash.
Also move the slicing-by-8 implementation (back) to src/port. This is in
preparation for next patch that will add another implementation that uses
Intel SSE 4.2 instructions to calculate CRC-32C, where available.
This is a long-standing inconsistency that was probably just missed when
we got 64 bit MSVC builds. This brings the platform into line with all
other systems.
As with initdb these programs need to run with a restricted token, and
if they don't pg_upgrade will fail when run as a user with Adminstrator
privileges.
Backpatch to all live branches. On the development branch the code is
reorganized so that the restricted token code is now in a single
location. On the stable bramches a less invasive change is made by
simply copying the relevant code to pg_upgrade.c and pg_resetxlog.c.
Patches and bug report from Muhammad Asif Naeem, reviewed by Michael

It worked in my Windows VM with VS2013, but buildfarm animal mastodon,
running MSVC 2005, was not happy. Amit Kapila also reported a similar error
earlier in his environment. Let's see if this helps.
Earlier versions of this tool were available (and still are) on github.
Thanks to Michael Paquier, Alvaro Herrera, Peter Eisentraut, Amit Kapila,
and Satoshi Nagayasu for review.
Instead of copying xlogreader.c and *desc.c files into the source directory,
build them where they are. That's what we do for other binaries that need to
compile and link in files from elsewhere in the source tree.
The commit history suggests that it was done this way because of issues with
older versions of MSVC. I think this should work, but we'll see if the
buildfarm complains.
Since commit cb4a3b04 we were already doing this for the Cygwin/mingw
toolchains, but MSVC had not been updated to do it. At Install.pm time,
the Makefile (or GNUmakefile) is inspected, and if a line matching
SO_MAJOR_VERSION is found (indicating a shared library is being built),
then files with the .dll extension are set to be installed in bin/
rather than lib/, while files with .lib extension are installed in lib/.
This makes the MSVC toolchain up to date with cygwin/mingw.
This removes ad-hoc hacks that were copying files into bin/ or lib/
manually (libpq.dll in particular was already being copied into bin).
So while this is a rather ugly kludge, it's still cleaner than what was
there before.

Previously, you could do \set variable operand1 operator operand2, but
nothing more complicated. Now, you can \set variable expression, which
makes it much simpler to do multi-step calculations here. This also
adds support for the modulo operator (%), with the same semantics as in
C.

Code like
open(P, "cl /? 2>&1 |") || die "cl command not found";
does not actually catch any errors, because the exit status of the
command before the pipe is ignored. The fix is to look at $?.
This also gave the opportunity to clean up the logic of this code a bit.
The meta data of PGLZ symbolized by PGLZ_Header is removed, to make
the compression and decompression code independent on the backend-only
varlena facility. PGLZ_Header is being used to store some meta data
related to the data being compressed like the raw length of the uncompressed
record or some varlena-related data, making it unpluggable once PGLZ is
stored in src/common as it contains some backend-only code paths with
the management of varlena structures. The APIs of PGLZ are reworked
at the same time to do only compression and decompression of buffers
without the meta-data layer, simplifying its use for a more general usage.
On-disk format is preserved as well, so there is no incompatibility with
previous major versions of PostgreSQL for TOAST entries.
Exposing compression and decompression APIs of pglz makes possible its
use by extensions and contrib modules. Especially this commit is required
for upcoming WAL compression feature so that the WAL reader facility can
decompress the WAL data by using pglz_decompress.
Michael Paquier, reviewed by me.
Backpatch to 9.3 where src/common was introduce, because a bugfix that
needs to be backpatched, requires the function. Earlier branches will
have to duplicate the code.
Windows versions later than Windows Server 2003 map "localhost" to ::1.
Account for that in the generated pg_hba.conf, fixing another oversight
in commit f6dc6dd5ba. Back-patch to 9.0,
like that commit.

This reverts commit 60838df922.
That change needs a bit more thought to be workable. In view of
the potentially machine-dependent stuff that went in today,
we need all of the buildfarm to be testing those other changes.
Exposing compression and decompression APIs of pglz makes possible its
use by extensions and contrib modules. pglz_decompress contained a call
to elog to emit an error message in case of corrupted data. This function
is changed to return a status code to let its callers return an error instead.
This commit is required for upcoming WAL compression feature so that
the WAL reader facility can decompress the WAL data by using pglz_decompress.

Back-patch to 9.0 (all supported versions). This is mere
future-proofing in the context of the master branch, but commit
f6dc6dd5ba requires it of older branches.
Use SSPI authentication to allow connections exclusively from the OS
user that launched the test suite. This closes on Windows the
vulnerability that commit be76a6d39e
closed on other platforms. Users of "make installcheck" or custom test
harnesses can run "pg_regress --config-auth=DATADIR" to activate the
same authentication configuration that "make check" would use.
Back-patch to 9.0 (all supported versions).
Security: CVE-2014-0067
The old pattern would match files with strange extensions like *.ry or
*.lpp. Refactor it to only include files with known extensions, and to make
it more readable.
Per Andrew Dunstan's suggestion.
These comments don't seem to have been touched in a long time. Make them
describe the current implementation rather than what was here last century,
and be a bit more explicit about the unreferenced-typedefs issue.
pg_atomic_init_u64 (indirectly) uses compare/exchange to guarantee
atomic writes on platforms where compare/exchange is available, but
64bit writes aren't atomic (yes, those exist). That leads to a
harmless read of the initial value of variable.
